VMware vRealize Automation makes it easy for us to provide our end users with the ability to request and manage their own virtual machines using a “self-service” portal. With very little configuration required, we can add vSphere virtual machine templates to a vRA service catalog for users to consume. vRA can then handle the request management for new virtual machines and when approved by the appropriate approvers, even provision the new VMs by cloning the template.

I remember struggling to get my head around Apache Webserver file permissions. It's a common issue, and I've seen forum posts this weekend with users struggling to get it right. That s what's prompted this post.

To allow the Apache web server process (httpd) to access and serve files from virtual host directories, httpd requires at least read access. However, with content management systems, httpd might also require write access to virtual host directories.

I've always wanted to find a cost effective way to implement 2-factor authentication. Commercial solutions are expensive, and if you are a small business, you might not want to spend a small fortune on implementing an enterprise solution with hardware tokens. I stumbled across Google Authenticator a while back and started to wonder how it can be used to implement a free 2-factor authentication solution in my lab. I also found a few posts that suggested teaming it up with Freeradius and that's really where this post started.

Administrators that's got some experience in running Linux guest operating systems in virtual machines, may know that the time of the guest OS can drift by several hours per day. Normally, in my experience the time in the guest OS runs too fast. This can have serious implications on some services that these servers provide, such as Mail/Spam relays and web servers.

VMware has now released a very good KB article on best practises for Linux Guest OS time keeping, with a table of kernels and their parameters.

The KB article is a must read for those who have Linux guests. You can find VMware KB Article 1006427 here
